Three methods to measure the bulk density

       

There are three methods to measure the bulk density of powder: Funnel method; Scott volumeter method; Vibrating funnel method.

1. Funnel method. The powder falls freely from the funnel hole at a certain height to fill the cup.

2. Scott volumeter method. The powder is put into the screen of the upper combined funnel, flows into the distribution box freely or by external force, alternately passes through four glass plates with an inclination angle of 25 ° and a square funnel in the distribution box, and finally falls freely from the funnel hole at a certain height to fill the cup.

3. Vibrating funnel method. The powder is loaded into a funnel with a vibrating device and vibrated under certain conditions. With the help of vibration, the powder falls freely from the funnel hole at a certain height to fill the cup. For the powder that can flow freely under specific conditions, the funnel method is adopted; For non free flowing powders, the latter two methods are used.
